CAP FOR VESSELS.

Specification of Letters Patent.

' Patented Dec. 12, 1905.

Application filed October 11,1904. Serial No. 228,010.

To all whom it may concern:

Be it known that I, JAMES MILNOR HroKs, a citizen of the United States, residing at Summit, county of Union, State of New Jersey, have invented a new and useful Improvement in Caps for Vessels, of which the following is a specification.

My invention relates to means for securing sealing-caps on vessels; and it consists in certain elements and combinations of elementsful'ly specified andv claimed in the following specification.

In order that those skilled in the art to which my invention appertains may understand, construct, and use my invention, I will proceed to describe it, referring to the accompanying drawings, forming a part of the specification.

Figure 1 shows an elevation of a bottle having a circumferential bead upon the outside of its neck, near the top thereof, provided with vertical cut-outs or grooves therein and showing a sealing-cap (shown in dotted lines) placed above the said bottle previous to being closed down on the bottle-mouth. Fig. 2 is a top view of the bottle, showing the said bead outs in said bead.-

E is a circumferential groove beneath bead F is the sealing-cap cup-shaped and having a top surface and a pendent flange Gr dropped, from the outer diameter of said top surface.

H represents fine circumferential furrows impressed in the inner surface of the flange Gr, but not corrugations.

J is the top surface of another form of cap having fine corrugations instead of furrows in the flange Gr disposed circumferentially.

L is a sealing-disk located in cap F.

The operation of my invention is as follows: After the bottle has received its contents the cap F of either construction, whether furrowed or corrugated, is placed over the mouth of the bottle with its sealing-disk in it or with a stopperentered in the bottle or on it and forced downward until the furrows H or corrugations K take onto and over the edges of the bead C and the compression of the sealing material has been suflicient to securely seal the bottle-mouth. The furrows in the cap-flange seizing the edges of the bed C prevents the cap from rising until removed by a tool for the purpose in a well-known manner. As many of the bottles in use vary from each other in depth of head and in diameter of bead and as the furrows H are very fine and close together, no matter how much the depth of the head is the great number of furrows permits one to seize the bead and hold the cap firmly. Of course the internal diameter of.

the cap F as to its pendent flange G is slightly smaller than the diameter of the bead C, so that there will be a springing of the material of the cap outward in forcing it over the bead C and a consequent returning toward its original size after the furrows or a furrow have passed the edge of the bead.

I have shown the cut-outs D in-the bead; but a continuous bead is sometimes used instead. The cut-outs are for the purpose of permitting the cap to be removed by a common instrument not particularly designed for the purpose, such as a wire or knife or any instrument which will enter the spaces beneath the flange G of the cap. Whatever is true of the cap and furrows is true as to the corrugations, but in a less degree.

Having now fully described my invention and the manner in which I have embodied it, what I claim as new and as my invention, and desire to secure by Letters Patent, is

1. In a means for sealing vessels, the combination consisting of a vessel provided with a circumferential bead upon the exterior of its neck and having the lower edge of said head sharply defined: a sealing-cap having a top surface and a flange p'endent from its outer diameter and provided with, circumferential furrows on the inner surface of said flange, whereby when the said cap is compressed upon the sealing material on the bottle-mouth, the furrows grip the lower edge of said bead of and retain said cap firmly in place regardless the variations in the dimensions of said bead, substantially as specified.

2. In a means for sealing vessels, a sealing I against removal, by the pressure from within member consisting of a metallic cap substantially cup-shaped, and provided on its substantially vertical surface with continuous horizontal furrows, a vessel having a bead near its mouth presenting an engaging surface at its lower extremity, and a groove beneath, whereby the said metallic cap by engaging by one of its furrows with the said 1 lower part of the said bead is securely held the vessel, substantially as specified.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 10th day of October, 5
